For the one-dimensional linear kinetic equation with collision frequency proportional to the module of molecular velocity, analytical solutionsof problems on temperature jump and weak evaporation (condensation) are received. Diffusively boundary conditions are considered. Quantities of jumps of temperature and concentration are found. Distributions of concentration, mass velocityand temperature are constructed. Necessary numerical calculations and graphic researches are done.

The solution of Couette problem in the flat channel is constructed. As the main equation the model of Bhatnagar-Gross-Krook (BGK) with almost specular boundary conditions is used.

It was found that intermodular vibrational spectra of Van der Waals clusters, calculated by ab initio methods have power-law dependence on the frequency, like crystalline bodies. However, the argument d_f of their spatial dimension, in contrast, for example, from the three-dimensional wave space d_f = 3 (the Debye law), take the values d_f<1, d_f=0, and may even be negative. Substances with dimension of spectra d_f <0, previously were not found.

Within quasichemical cluster model of real gas empirical parameters of Van der Waals equation of state are derived in terms of equilibrium constants of reactions of dimerization of gas monomers. Comparison of the theoretical results received with the available experimental data for argon is carried out.

In this paper chemical and vibrational relaxation of the five component air mixture behind shock waves is studied numerically on the basis of the three-temperature and one-temperature kinetic theory approaches. The influence of vibrational nonequilibrium as well as anharmonicity effects on the rates of exchange chemical reactions and macroscopic flow parameters in relaxation zone behind shock waves is estimated for different Mach numbers.

The interactions between V and Mn ions in semiconducting glasses of the system BaO-V₂O₅ are investigated by EPR. The influence of these interactions on the electrical properties of barium-vanadate glasses after an addition of Mn₂O₃ is studied. The electrical conductivity of barium-vanadate glasses decreases with increasing content of Mn₂O₃. It is proposed that this decrease is associated with the formation of pairs Mn²⁺-V⁴⁺, related exchange interaction as well as with the formation of large clusters of the ions V and Mn³⁺, Mn⁴⁺. This phenomenon can lead to a change of V-V distances. The pairs and large clusters make a direct contribution to the activation energy of hopping small polarons.

Change in the gradient of gas density in the shock wave front in He containing (0.1 - 1.0)%Xe is measured using the laser schlieren method in the range of Mach numbers M = (2.8 - 3.1) at equilibrium pressures behind the shock front P = (0.4 - 0.6) atm. It is found that the length of the shock front in this range increases linearly with the concentration of Xe.

Abstract, This article discusses the selection and application of the thin-film electroluminescent indicator synthesis method. thin-film electroluminescent indicators parametric synthesis and structural-parametric synthesis methods were studied by the group of authors. A comparison of thin-film electroluminescent indicators synthesis methods allowed to identify structural and parametric synthesis as the most effective, due to the simplicity and the search formalizing possibility for the optimal design solution with direct device structure and parameters handling during the search.

In this paper, using the average over the random phases justified quasi-linear kinetic equation for unstable and weakly ionized, non-isothermal plasma placed in a microwave electric field. Collisions accounted for by the Boltzmann collision integral.

Brief description of the main provisions of the new theory of external influences on the processes in condensed matter. The main attention is paid to the processes at the phase boundary and associated phase transitions in metals and alloys. Developed new methods that take into account external influences on these processes in liquid and solidified environments. Method of nonequilibrium thermodynamics is investigated insufficiently known processes of relaxation and dissipation of energy in the melt. For the first time revealed the relationship of the amount of external energy required for continuous crystallization of a unit volume of the melt and the metal structure in the solid state.
